Barlow fuzzy
I recently bought the National Geographic 76/700 EQ for my kids to look at the moon and planets. I'm not expecting much!
But have hit one major issue when it comes to the Barlow lens and I hope that someone can help.
When I look at the moon for example, it is sharp and clear with all the eyepieces. But when I try to add in the 2x Barlow that came with the telescope I find that I wind the focus in and the image gets sharper, but it doesn't fully sharpen before I hit the limit of travel.
Looking at other threads I can see that the actual Barlow is probably not great quality so may not be perfect, but the fact that it seems to be continuing to get sharper until I run out of travel makes me wonder if there is another issue at work here?
Can anyone help? Thanks in advance!
